The Netherlands Cancer Institute has a very strong history in
the generation and validation of mouse models of human cancer. Many
conditional mouse strains for tumor suppressor alleles often lost
or mutated in human cancer, such as Trp53, PTEN and Cdkn2a, have
been generated here and are routinely used worldwide. In that
context, the transgenic core facility accommodates all activities
required to generate genetically modified animals, from DNA and
Embryonic Stem Cell (ESC) services to transgenic services, such as
ESC microinjection, zygote injection as well as cryopreservation.
State-of-the-art technologies, such as ESC re-derivation from
complex models and genome editing, are also offered.
The transgenic core facility is part of the Mouse Clinic for
Cancer and Aging (MCCA). The MCCA is a collaboration of the
Netherlands Cancer Institute and the European Research Institute
for the Biology of Ageing in Groningen, The Netherlands. The MCCA
is funded by a Roadmap grant from the Netherlands Organisation for
Scientific Research (NWO).

Generating genetically engineered mice is a complex process that
requires a good strategy and detailed planning. In consultation
with the researcher we provide advice on the strategy and construct
design for generating the mouse strain tailor-made to answer a
biological question. Depending on the complexity and workload a
practical plan is devised to reach that goal and in some case might
involve participation of the researcher in cloning and/or ESC
culture. Our services are listed below and include cryopreservation
of new and existing strains.
- Generation of targeting and Flp-in constructs
- Design screening PCRs for targeting constructs
- Design and cloning of CRISPR gRNA plasmids
- Design ssODN for homology directed repair
- ESC re-derivation and cryogenic storage
- ESC quality testing
- Targeting and Flp-in of ESCs
- PCR and Southern blot screening
- ESC micro-injection/generation of chimeric mice
- Zygote injection; RNA and/or DNA injection
- Cryopreservation - sperm
- Cryopreservation - embryo
